TiffBitmapDecoder Class
Defines a decoder for Tagged Image File Format (TIFF) encoded images.
Assembly: PresentationCore (in PresentationCore.dll)
The following examples show how to decode and encode a Tagged Image File Format (TIFF) image using the specific TiffBitmapDecoder and TiffBitmapEncoder objects. For the complete sample, see TIFF Encoder and Decoder Sample
This example demonstrates how to decode a TIFF image using a TiffBitmapDecoder from a Uri.
' Open a Stream and decode a TIFF image Dim imageStreamSource As New FileStream("tulipfarm.tif", FileMode.Open, FileAccess.Read, FileShare.Read) Dim decoder As New TiffBitmapDecoder(imageStreamSource, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default) Dim bitmapSource As BitmapSource = decoder.Frames(0) ' Draw the Image Dim myImage As New Image() myImage.Source = bitmapSource myImage.Stretch = Stretch.None myImage.Margin = New Thickness(20)
This example demonstrates how to encode a BitmapSource into a TIFF image using a TiffBitmapEncoder.
Dim width As Integer = 128 Dim height As Integer = width Dim stride As Integer = CType(width / 8, Integer) Dim pixels(height * stride) As Byte ' Define the image palette Dim myPalette As BitmapPalette = BitmapPalettes.WebPalette ' Creates a new empty image with the pre-defined palette Dim image As BitmapSource = System.Windows.Media.Imaging.BitmapSource.Create( _ width, height, 96, 96, PixelFormats.Indexed1, myPalette, pixels, stride) Dim stream As New FileStream("new.tif", FileMode.Create) Dim encoder As New TiffBitmapEncoder() Dim myTextBlock As New TextBlock() myTextBlock.Text = "Codec Author is: " + encoder.CodecInfo.Author.ToString() encoder.Compression = TiffCompressOption.Zip encoder.Frames.Add(BitmapFrame.Create(image)) encoder.Save(stream)
